The Automatic Vent Opener was made to automatically control the temperature and humidity amounts and provide additional ventilation when needed, making gardening easier. As the surroundings within the greenhouse warms, the vent steadily opens to allow the correct amount of air flow into the greenhouse and closes when the temperature cools. The vent arm was made with a steel cylinder containing wax which expands when heated to push a piston, which raises the windows, as the atmosphere gets warmer, then agreements as it cools, closing with the use of a springtime and resetting the piston. All you need to do is usually to install it on your own roof vent windows and it immediately starts working. The Automatic Vent Opener operates without the use of electricity and is compatible with all Palram greenhouse versions only. The solar driven Vent Opener will begin to open as temps within your greenhouse reach 68 degrees F with full-open at 80 degrees. It installs efficiently and will provide care-free ventilation.
Ingenious temperature-sensitive device that automatically opens and closes coldframe lids, greenhouse windows and even skylights. Works during the day and maintain a Greenhouse Vent Opener constant interior climate, something extremely hard to accomplish by manual adjustments.
Requires simply no batteries or electricity.
It could be adjusted to start opening between 60-77°F. Fully open up at 86-90°F. Fully closed at 55°F.
Strongly recommended for every our glazed season extenders since it dramatically boosts plant growth.
The hydraulic cylinder comes with a 1 year warranty. The average lifetime of the cylinder is certainly 5-10 years, although some can last up to twenty years.
Screw straight into polycarbonate panels, wood, or metal frames. THE TYPICAL Vent Opener can open a hinged screen or vent weighing as much as 32 lb. For larger panes use the stronger Gigavent with all metallic building, to lift up to 65 lbs.
Note from the manufacturer: Suggested to lubricate the piston rod yearly, this can help extend the lifetime of the hydraulic cylinder. Don’t use solid grease, as dust particles “glues” easily onto the piston rod and will harm the rubber. Also don’t forget to unlock the vent in the wintertime if departing the vent openers installed. A good weak winter sunlight can warmth the hydraulic cylinder sufficiently to create it start pushing the piston rod outwards.
This solar vent control will open and close vents, in your solar gem greenhouse. It features two closing springs for extra power. The solar vent opener may be the only solar-operate control with a quick-release mounting bracket. Simply grasp the “clutch” arm and squeeze for easy detachment. This allows vent to be completely opened for access to the interior.
